Australian soap star Martin Lynes has been found guilty of sexual assault after he viciously attacked and bit a woman.

The 50-year-old Australian actor had entered a not guilty plea at the start of court proceedings, but on Wednesday at the Gosford District Court he was found guilty of aggravated sexual assault, and had his bail revoked.

Lynes, who starred in Home and Away , was handed a guilty verdict on one charge but was found not guilty on two other sexual assault charges.

The trial centred around allegations that Lynes had attacked the woman in 2015 and 2016 at a home in Bateau Bay on the New South Wales Central Coast.

The court had heard Lynes, best known in Australia for his role as Luke Forlano in All Saints, grabbed the woman by both breasts and threw her to the floor before biting her on the nose and sticking his finger in her anus.

The first case of alleged sexual assault is said to have taken place in May 2015 when Lynes questioned the woman about another man and is said to have become enraged.

He is said to have pinned the woman down on a bed and forced her legs open before assaulting her with a sex toy.

Lynes had denied the assault to police and argued he was forced to restrain the woman after the pair argued.

He well be sentenced in October for the guilty verdict that was returned of aggravated sexual assault.

Since 2014 Lynes has been working as a real estate agent on the Central Coast, but before that he played the role of Adam Sharpe on Home and Away from 2012-2014.

His first big break came in 1998 when he was cast in long-running Aussie drama All Saints.
